MC10EP57, MC100EP57
3.3V / 5V ECL 4:1
Differential Multiplexer
Description
The MC10/100EP57 is a fully differential 4:1 multiplexer. By
leaving the SEL1 line open (pulled LOW via the input pulldown
resistors) the device can also be used as a differential 2:1 multiplexer
with SEL0 input selecting between D0 and D1. The fully differential
architecture of the EP57 makes it ideal for use in low skew
applications such as clock distribution.
The SEL1 is the most significant select line. The binary number
applied to the select inputs will select the same numbered data input
(i.e., 00 selects D0).
Multiple V
BB
outputs are provided. The V
BB
pin, an internally
generated voltage supply, is available to this device only. For
single−ended input conditions, the unused differential input is
connected to V
BB
as a switching reference voltage. V
BB
may also
rebias AC coupled inputs. When used, decouple V
BB
and V
CC
via a
0.01
mF
capacitor and limit current sourcing or sinking to 0.5 mA.
When not used, V
BB
should be left open.
The 100 Series contains temperature compensation.
